Patent JP-S6348469-A (JP)
Title: Detection circuit
Inventor: SAEKI TAKAHARU
IPC: G01R19/22
Filed: 1986-08-19
Abstract: PURPOSE:To improve the frequency response characteristics of a detecting circuit by coupling the emitter signal of an output transistor (TR) with the base of a TR connected in parallel to the uninverted output side load circuit of a differential TR couple. CONSTITUTION:The collector potential of the uninverted output side TR Q3 in the differential TR couple of Q3 and Q2 is the base-emitter voltage of a parallel TR Q6 lower than the voltage at the output terminal 4 of this detecting circuit through the TR Q6 connected in parallel to the load of the circuit. Further, when a signal to be detected which is inputted to the base of the TR Q2 in the differential TR couple drops, the collector potential of the uninverted output side TR Q3 does not rise. Consequently, the TR Q3 is never saturated even if the base voltage of the TR Q3 becomes about 0.7V lower than that at an output terminal 4 and the input voltage drops below a detection voltage.

IPC: C04B38/02
Filed: 1993-08-04
Abstract: PURPOSE:To obtain a porous ceramic sintered compact, capable of achieving a higher porosity and having open cells by using a specific ceramic powder as a raw material and enabling the uniform dispersion of fine bubbles in a ceramic slurry and holding the bubbles therein. CONSTITUTION:This method for producing a porous ceramic sintered compact is to mix at least one of truly spherical silicon dioxide powder having 0.05-5mum average grain diameter and a grain size distribution within one digit in width thereof and truly spherical aluminum oxide powder having 0.05-5mum average grain diameter and a grain size distribution within one digit in width thereof with a solvent and a foaming agent, forming a slurry, then expanding the slurry, forming a foam, drying and sintering the resultant foam. Since the raw material ceramic powder has the specific grain size distribution and is truly spherical, the cohesive force of the powder is strengthened. Furthermore, since the raw material powder has the specific average grain diameter, a stable fine three- dimensional network structure can be obtained from the foam of the slurry in a stable dispersion state at a high concentration even if the liquid content is low.

Title: Laser beam butting welding device for material different in thickness, welding system and welding method
Inventor: TARUI HIROSHI
IPC: B23K26/21
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To guarantee the quality of the whole body of a welded product by irradiating a butting surface with a single wavelength light having wavelength different from that of a machining laser beam from a thin plate side, measuring the brightness of a reflecting light and properly controlling the brightness. SOLUTION: The laser beam oscillated from a laser beam oscillator 19 is condensed by a beam condensing optical system 20 to form the laser beam 1. The single wavelength light 10 oscillated from a single wavelength light generator 7 is emitted from the single wavelength light exiting end 9 through optical fiber 8 to irradiate each machining point 4. At this time, a butting surface is irradiated the single wavelength light 10 by an incident angle 11, and the reflecting light 12 of the single wavelength light 10 is reflected on the machining point 4 by the reflecting angle 16. Thereafter, the reflecting light 12 transmits a band-pass filter 13 capable of transmitting only the irradiating single wavelength light to form the reflecting light 14, and reaches a phototransistor 15.  Since the brightness of the single wavelength light 14 is measured and properly controlled, the quality of the whole body of the welded product can be guaranteed.

Consequently, a commutator 1 substantially has the total thickness of the rotating shaft 2 of the motor and the segments 10, and subminiaturization or a diameter of 0.5mm can be realized. Thus, peripheral speed is minimized to reduce the wear of the segments 10 and extend the life, and the amount of a noble metal contact material to be used is also reduced to reduce the cost. Further, the frictional loss with a brush elastically making contact therewith is also reduced, and output loss can be reduced.

Title: Level shift circuit
Inventor: NAKAYAMA KEIICHI
IPC: H03K5/003
Filed: 1986-08-20
Abstract: PURPOSE:To shift the low level and the high level of a digital signal by dividing the voltage between first and second power sources by resistances and connecting it to respective sources of P-channel transistor TR and an N-channel TR. CONSTITUTION:When a signal in the high level is inputted to an input signal terminal 1, a signal in a level (R2/(R1+R2+R3))VDD is outputted to an output signal terminal 2. When a signal in the low level is inputted to the input signal terminal 1, a signal in a level ((R2+R3)/(R1+R2+R3))VDD is outputted to the output signal terminal 2. Thus, the level of the output signal terminal 2 is (R2/(R1+R2+R3))VDD though the signal level of the input signal terminal 1 is changed from the level of VSS to the level of VDD, and a ratio of resistance values of resistances R1, R2, and R3 is changed to change the level of the output signal terminal 2 in a wide range. That is, the level of the digital signal is changed without changing a first supply voltage VDD.

Title: Pinhole detector for insulation film
Inventor: NIIKURA KATSUHIKO
IPC: G01N27/92
Filed: 1990-07-23
Abstract: PURPOSE:To enable detection to be free from effect of a change in charged current of an insulation film by arranging an insulation film charging electrode in front of an electrode which applies a voltage to an insulation film steel plate to be inspected to charge the insulation film with a potential the same in polarity as the electrode. CONSTITUTION:A power source 5 is connected electrically to an electrode 4 and a conveying roll 3 and the electrode 4 applies a voltage to an insulation film steel plate 1 to be inspected with the power source 5. A discharge current detector 6 detects a discharge current as caused by a pinhole existing in the insulation film 2 of the film steel plate 1 when the film steel plate 1 is conveyed below the electrode 4. The insulation film charging electrode 7 applies to the film 2 a potential the same in polarity as the electrode 4 from a power source 8. Then, the voltage is applied to the film 2 with the electrode 7 to charge and then, when the voltage is applied to the film steel plate 1 with the electrode 4 set therebehind 7, no current flows as the film 2 is already charged. Thus, a discharge current alone as generated when the pinhole exists in the film steel plate 1 is enhanced to be detected.

CONSTITUTION:Si oxide film 2 is formed on a semiconductor substrate, e.g. a p type Si substrate. Next, a resist pattern film 4 having a predetermined region 3 as an aperture is formed on the film 2 and then the film 2 is anisotropically etched with using the film 4 as a mask and is removed by etching selectively to the depth to remain a film thickness (w). Next, the film 2 of residual film thickness (w) is removed by wet etching to expose the region 3 of the substrate 1. Next, n type impurities are implanted in the region 3 by ion implantation to form n<+> type buried layer 5. After removal of the film 4, single crystal semiconductor 6 is epitaxially grown on the layer 5 and the polycrystalline layer 6' grown on the surface is then removed by etching, resulting in forming of a semiconductor 6 having flat isolation layer 2, i.e. the element forming region.

Title: Cleaning device of bath tub water
Inventor: KONDO NORIMASA
IPC: A47K3/00
Filed: 1994-07-27
Abstract: PURPOSE:To provide a cleaning device of bath tub water having a safe heater with a high heat transfer efficiency. CONSTITUTION:A metal heat transfer-type indirect heating device consists of a ceramic heater 16 sandwiched between two aluminum alloy metal housings with an embedded metal heat transfer pipe 14 through which hot water circulates. In addition, on the metal housing 15 of this heating device, a thermostat 18 is mounted which detects that a temperature reaches a specified level and sounds a warning for cleaning scale off the inner surface of a heat transfer pipe 14. If heating is indirectly safe, and a large amount of scale settling on the inner surface of the heat transfer pipe deteriorates the heat transfer efficiency of the heater 16, the thermostat 18 detects this deterioration leading to an increase in temperature of the metal housing, and sounds a warning to a user through a cleaning alarm device. Thus it is possible to clean the inner surface of the heat transfer pipe 14 at an appropriate time and thereby increase the heat transfer efficiency of the heater.
